The Fourier series is named in honor of Jean-Baptiste Joseph Fourier (1768–1830), who made important contributions to the study of trigonometric series, after preliminary investigations by Leonhard Euler, Jean le Rond d'Alembert, and Daniel Bernoulli. Fourier introduced the series for the purpose of solving … See more A Fourier series is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series, but not all trigonometric series are Fourier series. By expressing a … See more The Fourier series can be represented in different forms. The sine-cosine form, exponential form, and amplitude-phase form are expressed here for a periodic function See more When the real and imaginary parts of a complex function are decomposed into their even and odd parts, there are four components, … See more Fourier series on a square We can also define the Fourier series for functions of two variables $${\displaystyle x}$$ and $${\displaystyle y}$$ in the square $${\displaystyle [-\pi ,\pi ]\times [-\pi ,\pi ]}$$: Aside from being … See more This table shows some mathematical operations in the time domain and the corresponding effect in the Fourier series coefficients.

It is a generalization of the Fourier series, which is a way to represent a periodic function as the sum of sine and cosine functions.
